sensors-detect hangs up

[WebRider.ru]

Hello,

I've got a problem running lm_sensors. sensors-detect hangs up:

 BIOS vendor (ACPI): AMI
 System vendor (DMI): Gigabyte Technology
 BIOS version (DMI): 0700xx
 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no): yes
Probing for PCI bus adapters...
Use driver `i2c-piix4' for device 00:0f.0: ServerWorks OSB4 South Bridge
Probe succesfully concluded.

 We will now try to load each adapter module in turn.
Load `i2c-piix4' (say NO if built into your kernel)? (YES/no):yes
Module loaded succesfully.
 Do you now want to be prompted for non-detectable adapters? (yes/NO): no
 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
 i2c-dev is not loaded. Do you want to load it now? (YES/no): yes
Next adapter: SMBus PIIX4 adapter at 0580 (Non-I2C SMBus adapter)
Do you want to scan it? (YES/no/selectively):yes

And at this point the system hangs up.

Logs contain the following information regarding lm_sensors:

Motherboard is Gigabyte 6etxdr. Hardware monitor is Winbond w83782d
I've tryed skipping SMBus scan, but ISA bus scan found no sensors.
I've tryed inserting w83781d manualy with
modprobe w83781d
or
modprobe w83781d init=0
System hangs up at once.

isadetect returns all ff
i2cdetect - hangs.
i2cdump 0 0x00 - hangs.

Kernel version is 2.4.18
i2c version 2.7.0
lm_sensors 2.7.0
